The wire wound filter element is a deep layer filter element, which is used for filtering with low viscosity and low impurity quality. It is made of textile fiber lines (polypropylene fiber lines, degreased cotton lines, etc.), which are precisely wound on the porous framework (polypropylene or stainless steel) according to specific processes. It has a honeycomb structure with sparse outside and dense inside, which can effectively remove suspended solids, particles, rust and other impurities in the fluid, and has excellent filtering characteristics.
